QOOOOOOOOOOOOOOO OOOOOOQOO W trzeases my invention may 0 subject matter of my WILLIAM H. ALLEN, or

To all whom itmay concern Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Methods of Desiccating Organic Matter, of which the tion.

has particular utility in the desiccation of human bodies in mausoleum crypts, although it is not confined to this particular use,

It has been proposed heretofore to desiccate organic matter, and particularly human bodies by maintaining over and around the bodya circulation of dry air, from which moisture has been extracted by chemicals I have found that the method mentioned above, that is the dry air method, is made more efiicient and that the desiccation can be produced in a shorter period of time if the air is heated to a predetermined temperature above that at which decay germs may 'be formed. I have found that a temperature of 110- F. is ample for this pur pose, although I prefer to maintain the temperature of the air in the compartment at about 115 F.

In one aspect, my present invention may be regarded as an improvement on the dry air desiccating methods, and in this respect be defined 1n subjecting the substance to which decay germs may develop. There has also been proposed and successfully carried out the desiccation of organic substances by sub ecting the same 'to the action of a mag- ,netic fiel or by a magnetic field assisted by a circulation of dry air. This method forms prior Patent N o.

- Inuny prior patent above referred to, the

method as defined in one of its more specific aspects, consists m-maintaining a circulation of cool dry air about the substance bemg desiccated,i.w e the substance is subected to the" action of the magnetic field.

ture would otherwise be below the decay germs may form. I have found, however, that it is not necessary to maintain the circulation of cool subjected to the action of the magnetic old, but that the rate of desiccation is enhanced if no attempt is made to cool the air, but rather if the air is heated to the point above described. I find also that my method of desiccati ng with a magnetic field and dry air c'nulation can be carried on much more inexpensively when the air is heated instead of cooled. This is true for the reason that I can dispense with any system of refrigeration, and can rely upon the heat due to the current in the magnet coil to heat the air around the substance being desiccated, and thus am enabled to employ smaller coil conductors.

Therefore, in its more specific aspect, my present invention may be defined as consisting in subjecting the substance to be desiccated to the action of magnetic field in a heated atmosphere, or in subjecting the substance to the action of a magnetic field and maintaining about the substance .1 circulation of air which is perfectly dry, and heating the air, the air being heated in any suitable mann'er, but preferably in the compartment by the current Which traverses the 0011. If the resistance of the magnet coil is not suilicient or otherwise suitable for this purpose, I may utilize a separate rheostat or heating resistance which may belocated 1n the compartment, although not necessarily S0- 1 y invention may further briefly be summarized as consisting in certain novel steps in the method of desiccating, as will .be described in the specification and set forth In the appended claims.

The accompanying sheet of drawings shows in conventional and simplified form, an apparatus which may be utilized in carrying out my method.

a coil 13, the primary purpose of which is to produce a desiccatmg magnetic field. The

eferring now to the drawings, 10 reprethat at which inthis winding so that the magnetic field will substance. Preferably an substance tobe desiccated will be placed with:

, the inlet opening 11', a circulation of dry air from Which moisture may be extracted in any suitable manner, but preferably by passing the same through or over a suitable chemical, which may be calcium chlorid.

If the circulation'of dry air is maintained,

the air may be heated by the current passing through the coil, but ll consider it within. the

' to heat the air indescope' o t my invention 'pendently of the coil, either before or after passing the same into the compartment 10.

Having thus described my invention, what,

I claim is:

l. The method ofdesiccating an organic substance which consists in subjecting the substance tothe action of a magnetic field which envelope the substance, m an atmosto the action of a intense phere heated above the temperature at' which decay germs may be formed.

2. The method of desiccating' organic matter which consists in subjectin the se to the action of a magnetic field t ops the substance, in an atmosphere heated to a point above 110 degrees Fahrenheit.

3. lE'he method of desiccating organic matter which consists in subjecting the same magnetic field that envelops the matter, and in heating the atmosphere about the matter by the magnetizing current, to a temperature above that at which decay germs may be formed.

4:; A method of desiccating which consists in subjecting the substance to be treated to the action of a magnetic field, which envelops the substance, and in maintaining a circulation of dry air around the substance, and in heating the air to a temperature above that at which decay germs may be formed by the magnetizing current.
